Bladder cancer spreading and looking for options next steps.

My wife was diagnosed with bladder cancer in early 2025. Due to heart issues and age, surgical procedures were not viable. She completed a full series of radiation/chemo followed by BCG treatments and we seemed to be making good progress. A scan noted a lung nodule, we had the lung biopsy this past Monday and reported results are metastatic high grade urothelial carcinoma. Any ideas, recommendations, suggestions or what we should expect from those who have been through this?
